Reaction Steps
To a solution of (4-bromothiazol-2-yl)methanol (1.30 g) and imidazole (600 mg) in THF (10 mL) was added dropwise tert-butyldimethylchlorosilane (1.60 mL), and the mixture was stirred at room temperature for 1 hr. 1N Hydrochloric acid was added, and the reaction mixture was extracted with ethyl acetate. The extract was washed with saturated brine, and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (1.90 g) as a colorless oil.
